The Mariners' 'tragic number' now stands at one after they were shut out by their archrivals.
SEATTLE — A crowd of 33,382 fans saw the Seattle Mariners' minuscule playoff chances frilled to its final thread after a 7-0 loss to the Houston Astros on Tuesday at T-Mobile Park.
The Mariners will need to win their final five games of the regular season and the Astros and Texas Rangers will need to lose their final five for Seattle to make its way into the playoffs.
Tuesday marked the 15th shutout loss of the season for the Mariners — tied for the third-most defeats in that specific fashion in franchise history.
"I think, what we've talked about over the course of the year, runners in scoring position has been an issue," Seattle manager Dan Wilson said in a postgame interview Tuesday. "We just haven't been able to convert a lot of times when we have traffic. ... That's kind of been a little bit of the story."
The crowd of 33,000-plus, which has seen its fair share of gut-wrenching losses at T-Mobile Park in 2026, saw Houston take control from the onset Tuesday and never let go of that advantage.
The Astros took control of the game 1-0 in the top of the first inning after American League MVP candidate and designated hitter Yordan Alvarez hits an RBI single to bring home shortstop Jeremy Pena.
Houston began the contest with four-straight singles without the Mariners recording an out. The Astros had the bases juiced with nobody out, but starting pitcher Logan Gilbert was able to get out of the jam without giving up more than Alvarez's single.
Houston was still able to pull ahead further even without cashing in with the bases loaded.
Astros first baseman Christian Walker hit a three-run home run to left field in the top of the third inning to extend his team's lead to 4-0. Just like the first inning, Gilbert allowed consecutive singles to begin the inning that set Walker up for his three-run shot.
"(The pitch to Walker) should have been a little more outside," Gilbert said after the game. "It was kind of middle-low. Not a great spot. It was 1-0 but still, you got to get it that spot we're trying to go to."
Gilbert's day ended after the fourth inning. He struck out three batters, walked three (one intentionally) and allowed four earned runs on 10 hits (one home run) in his four innings of work.
"Some good pitches, some bad ones," Gilbert said. "Either way, they found a way to hit it. Felt like they were just putting a bat on it, finding ways. Just got to do a better job of getting that under-the-zone swing-and-miss."
The Seattle bullpen was unable to slow the bleeding against the Astros lineup.
With Mariners left-handed reliever Jose A. Ferrer on the hill, Houston third baseman Isaac Paredes hit a solo home run in the top of the sixth to extend the visitors' advantage to 5-0.
Alvarez ended the game the way he started: putting runs on the board.
The potential MVP hit a two-run home run to right field in the top of the eighth for the eventual final of 7-0. The hit came off Seattle right-handed reliever Carlos Vargas.
The Mariners had a runner reach base safely every game except the ninth. They finished 0-for-3 with runners in scoring position and left nine stranded.
Seattle's inability to bring its base runners home was despite the Astros going through their own pitching troubles.
Houston starter Cristian Javier exited the game after two innings due to groin tightness. The bullpen combination of Miguel Ullola, Bennett Sousa, A.J. Blubaugh and Logan VanWey combined to strikeout seven batters, allowed three hits and issued three free passes (three walks, one hit-by-pitch).
The Mariners will look to do their part to keep its playoff chance alive in the second of the two-game series against the Astros at 7:10 p.m. PT on Wednesday.
George Kirby will start for Seattle and Ethan Pecko will start for Houston.
